According to the ch-aviation fleets advanced module, the first three MAX 8-200s for the Polish airline will be SP-RZA (msn 62314), SP-RZB (msn 62313), and SP-RZC (msn 62315). According to photos available online, the aircraft have already been painted into the Buzz livery and remain in storage at Renton airport.

However, the delivery timeline remains uncertain. While the B737 MAX Family, in general, has yet to be recertified following the grounding in mid-March 2019, the -200 variant has not yet been certified at all by the Federal Aviation Administration (FAA). The derivative of the MAX 8 has a higher capacity and an additional exit door. According to The Air Current, a "design issue" separate from the MCAS-related woes is likely to delay the certification of the -200 even more.

Ryanair (FR, Dublin Int'l) currently expects not more than ten B737-8-200s before the peak 2020 summer season due to a recently discovered design issue, Chief Operating Officer Neal McMahon wrote in a memorandum to pilots.

As reported separately by The Air Current and Aero.de, McMahon said the delay was related to an unspecified design issue with the second overwing exit. As a result, the Irish LCC now expects deliveries of the B737-8-200s to commence in May 2020 at the earliest, subject to the B737 MAX being ungrounded by all relevant authorities by that time.

The high-density B737-8-200 variant needs a separate type certificate. Boeing started the certification drive in January 2019 but had to halt it when the entire family was grounded in mid-March.

Ryanair initially planned to receive its first twenty-five B737-8-200s by the end of 2019 and another twenty-five during the first quarter of 2020. After the grounding of the B737 MAX, the Irish LCC revised the schedule and said it hoped to receive fifty-eight 8-200s by the peak summer season...
